GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 449) = 287360
GCD(640, 449) = ( 640 x 449 ) / 287360
= 640 / 449
= 640
Step2:
LCM(1, 897) = 897
GCD(1, 897) = ( 1 x 897 ) / 897
= 1 / 897
= 1
Step3:
LCM(1, 967) = 967
GCD(1, 967) = ( 1 x 967 ) / 967
= 1 / 967
= 1
So, Greatest Common Divisor of 640, 449, 897, 967 is 1
